Improvement in siphons



JOSEPH M. NAGLEE, OF PHILADELPHIA, PENNSYLVANIA..

IMPROVEMENT IN smi-ions.

Specification forming part of Letters Patent No. 49,3041, dated April 12, 1864.

To all whom it may concern:

Be it known that I, Jos. M. NAGLEE, of Philadelphia, Pennsylvania, have invented an Improvement in Siphons; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a siphon having a reservoir With an opening below the bend and in the long leg. and a cock or valve at or near the lower end of the same leg, all substantially as and for the purpose described hereinafter.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanyingdrawings, which form a part of this specication,Figure I is a vertical section of myimproved siphon; I1igs.2 and 3, detached sectional views ot part of the saine.

The short stem A of my improved siphon is bent at the upper end and so connected tothe top ofa reservoir, C, as to communicate therewith, and from the bottom of this reservoir projects the long stem B, the latter having a cock, D, at its lower end for a purpose described hereinafter. In the top of the reservoir C is an opening, a, in which lits a cork or plug, e.

The usual method of filling a siphon with iiuid, preparatory to putting the same in oper ation, is to apply the mouth to thelower end of the longer stem, or to a tube communicating with that stem, and by causing a partial vacuum compel the fluid into which the short stem is inserted to iill the siphon. Where this method is inadmissable, as when acids or other corrosive or deleterious iuids are to be discharged by the siphon, the desired partial vacuum is caused'by means of an exhaustingsyringe. Siphons in which the latter method is practiced are expensive, while the former plan is exceedingly inconvenient, and can only be used in siphons of small dimensions.

In using my improved siphon the cockD is in the first instance so` turned as to close the long stem, and the plug e is removed. The

stem A is then inserted into the fluid to be discharged, and a sufcient quantity of the latter is introduced through the opening a to till the stem B and reservoir (l. The plug eis then replaced and the cock D turned, so th at the uid may flow from the long stem B into any suitable vessel.

It will be apparent th at before the fluid first placed in the reservoir C is exhausted a partial vacuum must be caused inthe short stem, through which the iluid will pass into the reservoir, and thence through the long stem, and this passage of the Huid will be continued as long as the stem Ais immersed in the supply of the fluid and as long as the cock .D remains open. When the siphon has to be laid aside for future use, the cock D is closed and the stem A withdrawn from the supply of luid, the stem B and reservoir C remaining lled. The siphon is then deposited in such a position that the iiuidshall remain in the reservoir, so that when the siphon is again required t'or use the replenishing of the reservoir and stem B will be unnecessary.

Instead of a simple'opening and a plug, a, a stop-cock with a funnel, as shown by red lines, Fig. 3, may be combined with the reservoir.

I am aware that siphons have been formed with bulbous and other air-chambers at or near the bend thereof, and that pistons have been applied tosiphons in this locality. These devices I do not claim but What I claim as my invention, and desire to secure by Letters Patent, is-

A siphon having a reservoir, C, with an opening, a., below the bend and in the long leg, and a cock or valve., D, at or near the lower end of the same leg, all substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH M. NAGLEE.
